Steel pipes can be divided into two categories according to production methods: seamless steel pipes and welded steel pipes, and welded steel pipes are referred to as welded pipes for short.

1. According to the production method, seamless steel pipes can be divided into: hot-rolled seamless pipes, cold-drawn pipes, precision steel pipes, thermal expansion pipes, cold spinning pipes and extruded pipes.

Seamless steel pipes are made of high-quality carbon steel or alloy steel, and can be divided into hot-rolled and cold-rolled (drawn).

2. Welded steel pipes are divided into furnace welded pipes, electric resistance welding (resistance welding) pipes and automatic arc welded pipes due to their different welding processes. It is round welded pipe and special-shaped (square, flat, etc.) welded pipe.

Welded steel pipes are welded by opposite seams or spiral seams from rolled steel plates. In terms of manufacturing methods, they are divided into welded steel pipes for low-pressure fluid transportation, spiral seam electric welded steel pipes, direct coil welded steel pipes, electric welded pipes, etc. Seamless steel pipes can be used in various industries such as liquid pressure pipelines and gas pipelines. Welded pipes can be used for water pipes, gas pipes, heating pipes, electrical pipes, etc.

Steel pipe coating characteristics

Coated tubes include outer coated tubes, inner coated tubes, and inner and outer coated tubes. Commonly used coatings include plastics, epoxy resins, coal tar epoxy resins, and various glass-type anti-corrosion coating materials. Galvanized pipes are divided into KBG pipes, JDG pipes, threaded pipes, etc.

What is welding? What is the difference between ordinary welding

Gas welding is a welding method that uses the flame generated by themixed combustion of combustible gas and combustion supporting gas asthe heat source to melt the weldment and welding material and realizeatomic bonding. Electric welding uses electric energy to pressurize,heat, or both, with or without filler material to achieve atomicbonding of weldments.
